Generic AV cables and Resupported4/DisplayOut

I'm looking to display my iPhone (Iphone 4, jailbroken on 4.0.1) on my TV. I do not have a widescreen HD TV. I mainly want to watch Netflix but I'll likely use it for other things as well.

Now, I just ordered this set of cables:

However, apparently I should have ordered this one:

Now, what exactly could be different between these two cables internally whereas the cheap one apparently won't work with my phone but the expensive set will? Are they not both just RCA cables tied into a USB and the Apple 30 pin dock connector?

Secondly, I've found some threads about Cydia apps that make the "cheap" cables work. Resupported4 and TVOut2 or DisplayOut are the ones I've seen mentioned.

Does this mean with one of these apps I can use the "cheap" set when it arrives? OR do I need one of these apps AND the "expensive" set of cables?

Please somebody enlighten me

Well crap. And I checked those links before posting!

I edited the first post with new links

The cable that apple sells for $50 has a chip in it that authenticates it. I have yet to see any third party cable work with any newer iPod/iPhone - this includes my old nano. Let me know if that $30 one works for you.

Regarding jailbreak apps, I think you can only use VGA to connect to a monitor. I don't even know if they support audio.

Gotcha. Well, I guess the chip explains the price difference.

I've done some searching on here and on YouTube and it looks like people have done exactly what I'm looking to do with a combination of stuff from my first post. I just want to know which combination will work for my application

Judging by the description for Resupported4 it looks like Resupported4 is made specifically for the purpose of using generic/offbrand cables. And, in the description for Resupported4 it states that in addition to Resupported4, you need DisplayOut to actually display on the TV.

I *think* generic cables along with Resupported4 and DisplayOut should work for what I want to do. I'm mainly confused as to whether or not I need the more expensive ($30) generic cables (i.e., do the Cydia apps allow me to use the $7 cables and circumvent the needed "chip"? OR do I need to use the Cydia apps AND use the $30 cables with the assumed generic "chip"?)

Well, I bought the $7 cables

The auction for the $7 cables says it is NOT compatible with the iPhone 4 or any firmware version above 3.0 (I stupidly didn't recognize/realize this before buying), whereas the $30 cables say they ARE compatible with the iPhone 4. I was originally curious what could be different internally on them and I guess even these generic $30 cables have this "chip" and are basically clones of the $50 Apple ones.

I'm paranoid I'll need the $30 cables though but I'd hate to spend $30 "just to see" so I was hoping somebody here had already done this!

I found this video on YouTube but it still doesn't tell me whether or not his generic cables are the "cheap" or the "expensive" ones, and it's also not clear whether or not he's got audio in addition to video. I sent that kid a message about it so hopefully he'll be able to tell me something

Bump:

Got my $7 "cheap" cables in the mail today. Remember, the seller of these cables says they will NOT work for the iPhone 4 or on any other iPhone running firmware 3.0 or higher.

I downloaded Resupported4 and DisplayOut earlier today hoping my cables would come, and they did, so I hooked it all up.

And... drumroll.. it works. Audio AND video works. YouTube, Safari, pics, videos, everything. No lag or any issues at all and it orients videos and pictures properly.

Thanks for everybody's input!

FYI, as of this morning, you don't need DisplayOut to put Netflix on a TV screen. The latest app update (version 1.1.1) added video out support for iPhone 4 and iPod 4th gen. Obviously you'd still need Resupported4 to use non-chipped cables.

Yeah, I saw that and downloaded the update of Netflix

But I can't get Netflix to display out "natively". Any idea how I can get this to work?

I just want to see what difference there is (if any)

Actually, I just tried again, and last night I couldn't get anything. Today, I get sound but no audio when trying it "natively"
